..think of it as lightening the distributor.

Yep, that's about what I got, maybe a couple millimeters or so. I guess a person could grind out the entire end of the slot and open her up for even more adjustment, but the vacuum advance/retard can limits how much you can turn the distributor...as I think you found out as well.
I'm looking forward to the 1.0 gram weight reduction. Should shave off .0000000000000000000001 second from my lap time.
